Twisted Rib Vase

A twisted-rib vase with a softly bulged body and a gently flared rim. Twelve outward ribs spiral up the wall, fading to a smooth profile at the base and the rim. It prints upright with a small chamfer on the foot to avoid elephant's foot. Adjust the height, base radius, bulge and rib depth to reshape it, then fine-tune the rim flare, wall and floor thickness, rib count, twist and foot chamfer.
